Considering that the energy consumption of urban rail traction power supply system mainly comes from the influence of train operation status,in order to reduce the energy consumption of traction power supply system,an optimization simulation model for rail traction power supply system considering energy conservation and consumption reduction is designed.This model utilizes the actu-al running chart of rail transit trains to construct an energy consumption simulation model for the traction power supply system based on the actual running chart.After analyzing the current actual running information and system energy consumption status of the rail trac-tion power supply system,an energy-saving optimization model for the traction power supply system based on the improved pigeon swarm algorithm is constructed to maximize the energy consumption conversion rate of the traction substation system and the optimal design objective function for the train timetable,By using the improved pigeon swarm algorithm to solve this objective function,the optimal design solution for the train timetable during energy-saving and consumption reduction optimization of the traction power sup-ply system is obtained.The experimental results verify that this model can increase the energy consumption conversion rate of the track traction power supply system by 9.04％,with significant energy-saving and consumption reduction effects.
